Pavlo GorkunThyristor Diode Modules SKKH, SEMIPACK
Modules SKKH Semikron are monolithic design with dual topology of semiconductors (two switches): thyristor - diode type. Used in DC and AC circuits with loads to 570A and reverse pulse voltages up to 2200V.
Thyristor Diode Modules AMKH AS ENERGITM is a replacement, equivalent and alternative semiconductor device for SKKH Semikron.
SCR modules are housed in a SEMIPACK – industry-standard housing making it easy to integrate the device into existing equipment.
SEMIPACK family has three different internal constructions:
soldered construction (SEMIPACK 1) – the contact is established by solder layers;
bonded construction (SEMIPACK 0, 2, 3) – the connection between top electrode of the chips and DBCs is realized by bond wires;
pressure contact construction (SEMIPACK 3, 4, 5, 6) – the contact is established by pressure, solder free assembly.
The main (power) terminals are on the top of the case and are marked as 1, 2, 3 (common anode-cathode, cathode, anode). The control terminals are marked as 4 (K1), 5 (G1).
SKKH thyristor diode modules are used in various power equipment - power and control units, power regulators, AC regulators, converters, controllers of blast furnaces or chemical processes, welding equipment, and as rectifiers for AC converters.
Our company provides a quality guarantee for thyristor / diode modules of 2 years from the date of purchase. When supplying thyristor / diode modules, if necessary, we provide technical passport and certificate of conformity.
The final price of thyristor / diode modules depends on the class, quantity, delivery terms, manufacturer, country of origin and form of payment.
For questions regarding the acquisition of Power Modules, Thyristors, Diodes, send an email request to:
And we will provide you a commercial offer for delivery.
For a large number, we will provide an individual price!!!
We are open to manufacture products at our production facilities
according to your requests and technical task.

Recommendations for mounting power modules
Heatsink and Surface Specifications, Preparation
In order to ensure good thermal contact and to obtain the thermal contact resistance values specified in the datasheets, the contact surface of the heat sink must be clean and free from dust particles. It is useful to clean the mounting surface of the heat sink with wipes and an alcohol cleaner, e.g. isopropanol, right before the mounting process. The following mechanical specifications have to be met:
– Unevenness of heat sink mounting area must be ≤ 50μm per 100 mm
– Roughness Rz: < 10 μm
– No steps > 10 μm
Heat sink surface specification |
Applying Thermal Paste
Recommended to use stencil printing in order to apply thermal interface material. For SEMIPACK we recommend thermal paste thickness in the range from 50 μm to 100 μm. Applying thermal paste by means of roller is not recommended for mass production as reproducibility of an optimized thermal paste thickness cannot be guaranteed.
Mounting torque on heat sink MS
To secure power modules, the use of steel screws in combination with suitable washers and spring lock washers or combination screws is strongly recommended. The specified torque value must be observed.

| Mounting screw | 2 pcs M5x18 | 4 pcs M5x18 | 4 pcs M5x20 | 4 pcs M6x20 |
| Mounting speed | max. 300 rpm | max. 300 rpm | max. 300 rpm | max. 300 rpm |
| Pre-tightening torque | 0.6 Nm | 0.6 Nm | 0.6 Nm | 0.6 Nm |
| Final torque MS | 4.25–5.75 Nm | 4.25–5.75 Nm | 4.25–5.75 Nm | 5.1–6.9 Nm |
A pre-tightening torque and retightening to the given torque value is recommended. For the screwing process the speed has to be limited and soft torque limitation is recommended to avoid torque peaks, which may occur with pneumatic screwdrivers.
The screws must be tightened in diagonal order with equal torque in several steps until the specified torque value MS has been reached.
